[0023]
Next, the operation of the facility moving apparatus according to the present embodiment will be described.
[0024]
When the stage 1 is moved, air is supplied from the air sources 3 to the air bearings 2 so that the entire stage 1 is floated several tens of millimeters from the floor surface. This is because the air supplied to the air bearing 2 flows out to the lower surface of the porous mat 2a, and the mat 2a is pushed up by the pressure of the outflowed air.
[0025]
The flying height needs to be substantially uniform over the entire lower surface of the stage 1. For this reason, when there is an imbalance in the load of the stage apparatus, the air supplied to the air bearing 2 in a portion where a heavy load is applied. The amount needs to be higher than the others.
[0026]
In the present embodiment, since the rotation speed of each fan driving motor can be individually changed by the inverter, the stage 1 can be floated horizontally by adjusting the air amount individually. Further, by adjusting the rotational speed of the motor, the speed at which the support in each part of the stage 1, that is, in each area, can be controlled to be the same.
[0027]
The stage 1 thus surfacing can be easily moved and rotated by a slight traction force.
[0028]
Here, the stage 1 moves as shown in FIG. 7 in which a wire fixing pin 6c installed on the floor surface FL, a wire 6a wound around a winch 6 provided on the support 1b of the stage 1, and the wire 6a. Is carried out by a pulley 6b for guiding the guide and a guide roller 6d pivotably attached to the floor surface.
[0029]
That is, the winch 6 is provided with one wire take-up drum at each end of the shaft of one motor, and each drum has a clutch and a brake, and one drum takes up the wire 6a. In this way, the stage 1, that is, the support 1 b is moved by being guided by the guide roller 6 d attached to the floor surface at a predetermined interval at the side edge thereof, thereby moving the stage 1 to the target position without swinging left and right. Can do.
[0030]
Since the guide roller 6d can be removed from the floor surface after the stage 1 is moved, the guide roller 6d does not interfere with the floor surface.
[0031]
The stage 1 is turned by the winch 6, the wire 6a, the pulley 6b, and the wire fixing pin 6c, and the chuck 5 and the positioning pin 5c shown in FIG. That is, one drum of the winch 6 winds the wire 6a, thereby rotating the stage 1 around the single positioning pin 5b.
[0032]
Thus, after the stage 1 arrives at a predetermined position, two of the positioning pins 5b are sandwiched between two sets of positioning chucks 5 on the support 1b to position the stage 1. Further, if the supply of compressed air to each air bearing 2 is stopped, each air bearing 2 contracts, the stage 1 descends, and lands on the floor surface. In the case of the descent of the stage 1, as in the case of the rising of the stage 1, the speed at which the support in each part of the stage 1, that is, each area descends is made the same by adjusting the rotational speed of each fan driving motor individually. Can be controlled.
[0033]
